The Google Apps group is continuing to put out interesting updates. Just yesterday they announced the addition of mail migration capabilities. What does this mean you ask? Google now offers a way that users can migrate existing email data from an IMAP server into their Gmail accounts on Google Apps. Gmail will then organize the messages into conversation threads, and will be able to display the original sender, recipient, and date of messages; and convert existing mail folders into labels.
One of the big benefits of all this is that old messages become instantly searchable, using the Google powered search capabilities built into Gmail. This could be a big feature for companies that have large reams of archived email data that is generally hard to access.
Companies that could benefit might include those that are subject to governmental regulation in all their communications with their customers, such as stock brokerages. Fast easy access to all of that information could dramatically reduce costs in showing their compliance.
